It's interesting to me that Red Eclipse has such extensive support for changing how weapons work, but I never see it used.
I'd love to see other people's experiments with the weapon vars, and discussion of them. Ultimately, I'd even like to see custom vars multiplayer matches. Or even a custom var server.
I've included my own pack, for people to play with, have fun with, admire, pick apart, criticise and rage over. I'd like advice over what could be changed, or what you like. Some of it was from quite a while ago now, so I might even agree with you now.
My pack. There's a readme.
